Abstract: Gas turbine engine systems involving rotor bayonet coverplates and tools for installing such coverplates are provided. In this regard, a representative turbine assembly for a gas turbine engine includes: a turbine disk operative to mount a set of turbine blades; and a coverplate having an annular main body portion and a spaced annular arrangement of tabs extending radially inwardly from the main body portion with open-ended gaps being located between the tabs, the tabs being operative to secure an inner diameter of the coverplate to the turbine disk.

Abstract: A bearing assembly support and adjustment system includes an annular support device and an annular adjustment sleeve. The annular support device has a support device outer circumferential surface located about a first axis and a support device inner circumferential surface located about a second axis spaced apart from the first axis. The annular adjustment sleeve has an adjustment sleeve outer circumferential surface located about a third axis and an adjustment sleeve inner circumferential surface located about a fourth axis spaced apart from the third axis. The annular adjustment sleeve is coupled to the annular support device with the adjustment sleeve outer circumferential surface located immediately adjacent the support device inner circumferential surface.

The clock control module is configured to provide a first clock signal having a first frequency to the first functional unit in response to receiving a start signal. The clock control module is configured to provide the first clock signal to the second functional unit in response to receiving a first control signal from the first functional unit, and the clock control module is configured to stop providing the first clock signal to the first functional unit in response to receiving the first control signal from the first functional unit.

Abstract: A programmable calculator employs modular read-write and read-only memories separately expandable to provide additional program and data storage functions within the calculator oriented toward the environment of the user and two sixteen bit LSI NMOS central processing units. One of the central processing units (LPU) is employed to perform language syntaxing, arithmetic, and general supervision of program execution. The second central processing unit (PPU) is employed for managing input/output operations. Communication between the two central processing units is accomplished by an arrangement through which the two central processing units share a common portion of memory. The calculator also includes a keyboard having a full complement of alphanumeric keys for entering programs and data into the calculator and for otherwise allowing the user to control operation of the calculator.

Abstract: As a separable part of a multiple set of carbon interleaved forms for use with a computer terminal, the invention comprises a separable flap having a free lower edge and hingedly secured adjacent its upper edge to the upper end portion of the set with precisely located input area designations imprinted on its under surface for display in accurate relationship to the set forms when the free edge is lifted and swung upwardly through an arc of 180 degrees for insertion into the terminal, whereby following entry of the desired input area data on the flap, the latter may be separated from the set and discarded without wasting the hyperextended portions of a prior art set that have been required when the input area was disposed on the upper portion of the usual cover sheet.
